preparation example Construction

[0022] The invention discloses a method for preparing a platinum / cuprous oxide thin film composite, which is characterized in that: using copper flakes, dilute hydrochloric acid, copper nitrate, platinum acetylacetonate, and ultrapure water as raw materials to prepare the platinum / cuprous oxide composite, The platinum / cuprous oxide composite is a platinum cuprous oxide film loaded with turquoise in shape, and its appearance is crisscrossed linear, with a length of about 20 μm and a diameter of about 150 nm; specifically including the following steps:

[0023] (1) Use dilute hydrochloric acid to remove oxides on the surface of the copper sheet, and then use ultrapure water to wash the dilute hydrochloric acid on the surface of the copper sheet;

[0024] (2) Prepare 100ml of copper nitrate solution for use;

[0025] (3) Weigh the platinum acetylacetonate to dissolve, and put the platinum acetylacetonate dissolved in step (2) and the copper flakes washed in step (1) into the copper nitr...

Embodiment 1

[0033] (1) Cut the copper sheet into 1*1cm 2 , Soak in dilute hydrochloric acid to remove oxides on the surface of the copper sheet, and then wash the dilute hydrochloric acid on the surface of the copper sheet with ultrapure water, and set aside;

[0034] (2) Configure 100ml 5*10 -3 mol / L copper nitrate solution, ready for use;

[0035] (3) Accurately weigh 7 mg of platinum acetylacetonate and dissolve it. After dissolving, add the platinum acetylacetonate solution and the copper flakes in step (1) to the copper nitrate solution in step (2) above to grow at 40°C;

[0036] (4) After 1 day of growth, it can be observed that a layer of blue-green product has grown on the surface of the copper sheet. The product can be obtained by rinsing it with ultrapure water.

[0037] The product obtained in step (4) is subjected to XRD and XPS determination, such as Figure 1-3 As shown, figure 1 The middle spectrum shows obvious cuprous oxide, and the peak at about 42° is a copper base peak; fig...

Abstract

The invention discloses a preparation method and an application for a platinum / cuprous oxide film compound. The preparation method is characterized in that a platinum / cuprous oxide compound is prepared by taking a copper sheet, diluted hydrochloric acid, copper nitrate, platinum acetylacetonate and ultrapure water as raw materials, wherein the platinum / cuprous oxide compound is a platinum-loaded cuprous oxide film, is in a dark green and criss-cross linear shape, and has a diameter of 150 nm and a length of about 20 [mu]m. The preparation method provided by the invention is simple in preparation process, does not need to adapt to special production equipment, and facilitates popularization and production; meanwhile, compared with a traditional preparation method, the preparation method provided by the invention is easy to control the microtopography of the platinum / cuprous oxide film compound; the platinum / cuprous oxide film compound produced by using the preparation method provided bythe invention is used as a hydrogen energy catalyst and has excellent stability and good catalytic effect; economic benefits and social benefits are greatly improved; and the preparation method is worthy of popularization.

Description

Technical field [0001] The invention belongs to the field of electrocatalysis, and in particular relates to a preparation method and application of a platinum / cuprous oxide film composite. Background technique [0002] Energy is the material basis for human survival and is closely related to human life and social and economic development. With the rapid development of modern economy, people use more and more traditional fossil energy such as coal, oil, natural gas, etc. The shortage of energy and the pollution caused by excessive energy exploitation are becoming more and more serious. Therefore, the research and development and utilization of new energy Imminent. Existing hydrogen energy has attracted much attention as an efficient and ideal clean energy. Among many methods for preparing hydrogen, electrochemical water splitting is considered to be an effective method for sustainable hydrogen production. Therefore, people have started the research of hydrogen evolution electroca...
